Doug and Pat have pretty great gear show on Youtube, well worth subscribing to, if you're so inclined, I've been following them for a while. They have an amazing assortment of vintage gear, do comparisons with modern re-issues, top shelf stuff.
Their newest episode is on P90's. They demo a handful of 50's Gibbons and Modern Custom Shop Guitars.
They get to mine around the 28 minute mark.
Check it out.
